I have a TF radio. It is out of the truck and I would like to start at the first step of checking it out.
Can I connect a speaker, plug it into an antenna, ground it to the negative post of the battery, and connect the power wire to check if any noise comes out?
How can I check the on/off, fader switch if noise comes out of the speaker?
This seems to be the basic first step for a radio that I picked up at a swap meet for $5.
